1. What is the nature and description of the request?

Customer's on AAP 2.6 Containerized with external (not AAP managed) DB version 16 cannot backup/restore the platform using the provided backup/restore playbooks.

Actually only version 15 is supported.

This is very disrupting for customer's coming from AAP 2.4 as it is a regression for them. They can no longer backup/restore their platform.

The solution is pretty simple, I described it in the following document :

Our ask is that  :

1. The procedure is implemented by default in the bundle without further customization required, meaning :
   • the postgres-16 image (registry.redhat.io/rhel9/postgresql-16:latest) becomes included in the bundle
   • the image is automatically distributed by the backup playbook to the relevant nodes
2. This procedure becomes documented in official backup/restore documentation
3. This procedure becomes supported
